USRP

The data coming from the USRP1 is ± 32767 as the floating point range. In the USRP2 we use ± 1.0[1].

Filtering

If the decimation is a factor of four there are two half-band filters + CIC filter, if it is a multiple of two (i.e. even, but not a factor of four) then there is only one half-band filter + CIC, and if it is an odd number, just a CIC filter[2].

Note: Being a TV tuner, TVRX has 75 Ω input. When using 50 Ω cables and antenna, this will result in an SWR of ~ 1.5 (TBC), which is not that bad considering all other deficiencies of a TV tuner.
